This patent describes a new type of armor that's built like a LEGO set. Instead of one big, bulky piece, it's made from many small, strong blocks called "unidirectional composite bricks." Each brick has a core of strong fibers pointing in the direction of an incoming bullet, which helps it absorb energy much better than older designs. These bricks are then wrapped in a protective layer, either made of another composite material or metal. The best part is that if a part of the armor gets damaged, you don't have to throw the whole thing away. You can just replace the damaged bricks, making it much easier and cheaper to repair. This design also helps the armor withstand multiple hits and can be adjusted in size to protect against different types of threats.

This invention attempts to enhance the energy absorbing capacity of armour systems by modifying the mechanism of energy absorption by the composite material from flexural response to longitudinal compression. Additionally, when conventional fabric-based armors are damaged, they must be completely discarded, leading to significant waste and cost.
- Modular "Brick" Architecture: The armor system is built from a plurality of unidirectional (UD) composite bricks, allowing for localized repair and replacement of damaged sections, unlike conventional armors that require full replacement.
- Multi-hit Capability: The modular design and improved energy absorption contribute to a multi-hit capability, meaning the armor can withstand multiple impacts in different locations without complete failure.
- Optimized Fiber Orientation: Each UD composite brick has a fiber core oriented in the impact direction, leveraging the highest strength direction of the material for enhanced ballistic resistance. This contrasts with conventional designs that often arrange composite layers transversely.
Each brick would consist of a fiber core oriented in the impact direction, encased within a confinement unit and further protected by either a composite material jacket or a metal jacket. These bricks, potentially cylindrical, rectangular, or hexagonal, would be arranged in staggered or criss-cross patterns, and layers of armor fabric like Kevlar could be interspersed between them. The design emphasizes modularity for repair, enhanced ballistic energy absorption through axial compression, and multi-hit capability.
Proof of Concept (Experimental/Simulation or otherwise) (TRL 3)

There is a huge requirement for advanced armour technology in the armed forces in India, and this technology satisfies that need. Military personnel, law enforcement, and even civilians in high-risk zones could have access to lighter, more effective, and repairable body armor, significantly increasing their survivability in hostile environments. This could lead to a reduction in casualties and long-term injuries.
